Sam did notice that he hasn't seen this young man's face before, but he hasn't gone asking questions about the world yet, so he'll let that slide unless the boy brings it up.

"Go on, Dragonite. It's okay." At its human's word, Dragonite begrudgingly brings its nose down to rest against the boy's hand. It's warm, smooth, and scaly, with hints of the sheer power of the beast beneath. (A beast that was actually pretty easy to tame, since Sam raised it from an egg.)
